Please help with this quick 8th grade math question I'll give you best answer thanks! Dan and Mario went to a sandwich shop to buy sandwiches for their group of friends. Dan bought 2 tuna and 5 vegetarian sandwiches for $37. Mario bought 4 tuna and 3 vegetarian sandwiches for $39. Which system of equations can be used to solve for the cost of each kind of sandwich? I only need the system of equations please! =)

Nothing @latinC =(

you have two variables, first is tuna sandwiches which we will call T and the second is vegetarian sandwiches which we will call V. With these two variables make two sets of equations similar to this one V + T = SUM
